Flower Mound: a Town with six area codes?

Not sure if this will ever come to pass, but it's conceivable that Flower Mound could be one of only cities in the U.S. to have six area codes within its limits. You know that most of Flower Mound lies in the 972 area code, but there's the overlay with 214 and 469. I don't know if anyone in Town has a home or business phone with a 214 and 469 area code, but it's possible the phone company could create an exchange in any of the three area codes.

Same for the west side of town, which falls under the 817 area code. There's an overlay here too, so it's possible that someone in Flower Mound could have a home or business phone number in the 682 area code, which overlays 817.

That's five. What about the sixth? This is a stretch, but I think I'm right. There's a new subdivision being requested for the piece of Flower Mound that's north of 407, near Chinn Chapel. I think this piece of land is in the 940 area code - at least that's how it appears to me.

So 214, 972, 469, 817, 682, 940 -- all rooted in Flower Mound somewhere? Perhaps someone with the phone company will post a comment to debunk my logic, but how many other cities do you know that could claim six home area codes, even five (if you don't count 940)?
